Perhaps you should try some spelling variations:
"post modeling algorithm" » "post scheduling algorithm" (Expand Search), "most modeling algorithm" (Expand Search), "cost modeling algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"data backing algorithm" » "data banking algorithm" (Expand Search), "data lacking algorithm" (Expand Search), "data packing algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("elements method algorithm") OR ((("data backing algorithm") OR ("post modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data backing algorithm\") OR (\"post modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data backing algorithm ) OR ( post modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data backing algorithm") OR ("post modeling algorithm"))))*.
